Bristlecone pines
A new C-14 ancient pine cone solar activity reconstruction showed unusual cosmic ray events at 5480BC, 775 AD and 994 AD, so we can trace these effects through different societies on Earth at the time and see what happened in their local histories. China, Japan, Central Asia, Persia, Roman Empires. Now we overlap with current events on our planet, and the correlation is clear to see, repeating cycles of climate thousands of years apart.
